Are age spots dangerous?

A true solar lentigo (age spot) is benign — it's a harmless patch of extra pigment from years of sun exposure, and it won't turn into cancer. The catch is that a few skin cancers, especially an early melanoma called lentigo maligna, can look like an ordinary age spot in the beginning. So the spots themselves aren't dangerous, but any 'age spot' that is darkening, growing, developing uneven color, or otherwise changing should be checked by a dermatologist to be sure that's what it is.

What's the difference between age spots, melasma, and actinic keratoses?

All three are related to sun but differ. Age spots (solar lentigines) are flat, well-defined brown patches from cumulative UV, common on the hands and face. Melasma is larger, blotchy, symmetric brown patches driven by hormones plus sun, often on the cheeks. Actinic keratoses are rough, scaly precancerous patches you can often feel more than see. Because treatment and seriousness differ, it's worth having a professional confirm which you have.

Can I get rid of age spots at home?

You can often fade them, but slowly and only partially. Daily sunscreen is non-negotiable — without it, spots keep coming back — and ingredients like retinoids, vitamin C, azelaic acid, and niacinamide can gradually lighten them over months. Faster results usually come from in-office treatments like lasers, chemical peels, or cryotherapy. Have a dermatologist confirm a spot is actually an age spot before treating it, so you're not disguising something that needs attention.

Sun Spots & Age Spots (Solar Lentigines), Explained

Those flat brown spots that show up on the backs of the hands, the face, the shoulders, and the chest as we get older have a few names — age spots, sun spots, liver spots — but dermatologists call them solar lentigines (a single one is a solar lentigo). Despite the "liver" and "age" labels, they have nothing to do with your liver and everything to do with the sun. They're one of the most common, and most harmless, signs of a life spent outdoors.

The one important nuance: a true age spot is benign, but a few things can look like one and aren't — so it's worth knowing both the reassuring story and the carve-out.

What they are and what causes them

A solar lentigo is a well-defined flat patch of extra pigment caused by chronic UV exposure. Over years, ultraviolet light drives melanocytes to make and retain more melanin in that spot, leaving a lasting mark (DermNet). They're a form of hyperpigmentation — the same broad family as melasma and post-inflammatory dark spots, just with a different trigger and pattern.

Typical features (DermNet):

Flat (or very slightly raised), smooth, and well-demarcated.
Tan, brown, to dark brown, usually an even color within the spot.
A few millimeters to a centimeter or more across.
On sun-exposed skin: backs of the hands, forearms, face, upper chest, shoulders, and (in balding scalps) the head.

They're more common with age simply because sun damage is cumulative — but plenty of younger people who tan or use tanning beds get them too.

How they're different from the lookalikes

"Brown spot" covers a lot of ground, and the distinctions matter because the treatment and the stakes differ:

Age spot (solar lentigo): flat, even brown, stable, sun-exposed areas. Benign.
Melasma: larger, blotchy, symmetric patches, often on the cheeks/forehead; hormone- plus sun-driven.
Actinic keratosis: rough, dry, scaly — you feel it more than see it. Precancerous and needs a doctor.
Lentigo maligna: an early melanoma that can masquerade as a slowly enlarging, unevenly colored "age spot" (see below).

If you're not sure which you're looking at, that uncertainty is itself a good reason to have a dermatologist take a look.

The lookalike that matters: lentigo maligna

Here's the honest carve-out. Lentigo maligna is an early form of melanoma that develops on chronically sun-damaged skin — most often the face of older adults — and in its early stages it can be mistaken for a harmless age spot (StatPearls). What sets it apart is change and irregularity: a spot that is enlarging, darkening unevenly, developing multiple colors, or an asymmetric, blurred border.

An ordinary solar lentigo can slowly darken with sun over time, so slow change alone isn't an alarm — but uneven color, an irregular border, or a spot that stands out from your others (the "ugly duckling") should be assessed in person rather than assumed to be an age spot.

How to fade them

If a spot has been confirmed as a benign age spot, you can usually fade it — gradually and partially (AAD):

Daily broad-spectrum sunscreen is the foundation. Without it, spots deepen and new ones form, and any treatment you try will be undermined.
Topicals, applied consistently for weeks to months: retinoids, vitamin C, azelaic acid, niacinamide, and other brightening agents. Our how to fade dark spots guide covers realistic expectations and ingredient pairings.
In-office procedures work faster but cost more and carry more risk: cryotherapy (freezing), laser therapy, chemical peels, and microdermabrasion (AAD).

The AAD's first piece of advice is worth repeating: see a dermatologist before treating, because a professional can confirm a spot is truly an age spot — and not something that needs a different plan (AAD).

When to see a doctor

Age spots are harmless, but get a spot checked if it (StatPearls):

Is growing, darkening unevenly, or changing in shape.
Has an irregular or blurred border, or more than one color.
Itches, bleeds, crusts, or won't heal.
Stands out from your other spots, or is a new pigmented spot on the face of an older adult.

A private skin assessment can help you document a spot you want to track, but it is informational only — a changing or atypical pigmented spot should be examined by a dermatologist, who can tell an age spot from something that needs treatment.
